Question

elements such as carbon can move through the environment and organisms in a cycle because living and nonliving things interact in organisms. cells. species. ecosystems.

Explanation:

To solve this, we analyze each option:

• "Organisms" focus on living things only, not non - living interactions.
• "Cells" are the basic unit of life, not the level where living and non - living interact for element cycles.
• "Species" are groups of organisms, not including non - living components.
• "Ecosystems" include both living (biotic) and non - living (abiotic) components. Nutrient cycles like the carbon cycle occur within ecosystems as living and non - living things interact (e.g., plants take in carbon dioxide from the non - living environment and release oxygen, animals consume plants and release carbon dioxide back to the environment).

Answer:

D. ecosystems.
